Frequently asked questions
Quick answers about the SunSun XBL Hang-On Filter, drawn from its specs.
What size tank is the SunSun XBL Hang-On Filter good for?
Using the 5 to 12 times turnover rule for planted tanks: XBL-300 (300 L/h, suits roughly 25–60 L); XBL-400 (300 L/h, suits roughly 25–60 L); XBL-500 (500 L/h, suits roughly 42–100 L); XBL-600 (500 L/h, suits roughly 42–100 L). Real flow with media and hoses is lower than the rated figure, so pick the bigger model if you are between sizes.
